Fig. A: Laboratory demonstration of the ice formation. The container on the left side of the photo has a stratified fluid with pink corresponding to the heaviest fluid, clear/ice the lightest and the blue has an intermediate density. The container on the right side of the photo corresponds to an un-stratified one density fluid throughout. Both containers were placed in the freezer (in a manner that allowed them to be cooled only from the top) for the same amount of time. Ice is only visible in the left (stratified) container because the stratification prevented convection. Avoidance of convection permits ice to form on top of the stratified fluid much faster than it would in the homogeneous non-stratified fluid on the right, simply because, in the stratified case, there is much less fluid to cool down. The container on the left represents the "springs ice" (i.e., the region above the plume generated by the springs) whereas the container on the right represents the remaining unfrozen part of the lake.
Fig. B: Further illustration of how important stratification is to the cooling and warming of fluids. Here, we use heating and boiling, as opposed to cooling and freezing shown in Fig. A, to illustrate this point. The container on the left has two fluids; the green is the heaviest whereas the red is the lightest. The container on the right has a homogeneous un-stratified fluid. The burners below heated both containers for the same amount of time. As in the cooling and freezing case shown in Fig. A, the stratification prevents convection. Thus, the green fluid on the bottom of the left container is boiling while the fluid above it, as well as the fluid in the other container, are still not boiling. To demonstrate that, indeed, only the green fluid is boiling, I have placed my fingers in the red fluids. (Don't try this at home!) This process is the reverse of the "springs ice" formation shown in Fig.A.

How to teach Oceanographic in German?
Posted on 15 April 2024
For instance, concepts like "density" may be described by technical terms in German or Norwegian but are intuitive in English. In German, terms like "Dichte" or "tetthet" aren't commonly used in everyday language and require explanation, especially in subjects like oceanography. To help students grasp the concept, I often demonstrate density through experiments, such as how soda cans with the same volume can sink or float depending on their contents.
An online German tutor can be crucial in helping students understand oceanographic topics, even if the tutor is not a specialist in the field. By providing language support and clarification in German, the tutor can assist students in comprehending technical terms and concepts that may be challenging to grasp in a foreign language. Additionally, the tutor can offer explanations tailored to the student's level of proficiency, breaking down complex topics into more digestible segments and facilitating discussions to reinforce understanding. Through personalized guidance and encouragement, an online German tutor can empower students to engage confidently with oceanographic material and achieve academic success.
